She’s so worn out! Being pregnant isn’t easy and Kim Kardashian is feeling the pressure of trying to stay glam while dealing with the challenges of carrying her second baby. HollywoodLife.com has EXCLUSIVELY learned how Kim’s coping with the stress.

Kim knows how lucky she is, but that doesn’t make being pregnant any easier. “Kim loves being a mom and is so incredibly overjoyed to be pregnant. She is constantly reminding herself how lucky she is. Still, part of her is struggling with transitioning as she gets older. It’s hard because she feels fat and so so tired. Doing everyday things like parenting, exercising and working is exhausting. Kim doesn’t feel as good as she’s pretending to. Kim feels like she’s as big as a house, but refuses to give in and dress in unflattering maternity clothes,” a source tells HollywoodLife.com EXCLUSIVELY. It’s tough to be an international style icon and a mom at the same time.

Could her growing rivalry with her youngest sister be stressing Kim out? “She’s so happy to see her little sisters growing into beautiful women, but it’s hard not to be a little jealous,” an insider tells HollywoodLife.com EXCLUSIVELY. “Kim is definitely jealous of Kylie’s body and the fact that she doesn’t even work out to keep it looking like that. She gets worried sick that her fans will drop off as she gets older and less relevant to younger people, so she’s thinking of ways to stay in the public eye.” You’ll always be number one to us, Kim!
